FUEL-BURNER.

SPECIFICATION forming part of Letters Patent No. 794,5e5, dated July 11,1905.

Application filed April 14:. 1905. Serial No. 255,593.

To all whomit ntay concern.-

Be it known that I, THoMAs W. PHILLIPS, J r., a citizen of the UnitedStates of America, residing at Butler, in the county of Butler and Stateof Pennsylvania, have invented certain new and useful Improvements inFuel- Burncrs, of which the following is a specification, referencebeing had therein to the accompanying drawings.

This invention relates to certain new and useful improvements infuel-burners; and the object of the present invention is to provide aburner by the aid of which the fuel may be economically used and toprovide novel means for thoroughly mixing and commingling the fuel withair to increase the combustion.

The invention aims to provide means for artificially mixing air with afuel, such as gas, and a novel form of burner is employed for ejectingthe fuel into the mixing-chamber or air-tube at any desired angle to theaxes or radii of the mixing-chamber or air-tube.

My invention aims to further provide a novel form of burner which willbe inexpensive to manufacture, strong and durable, and highly efficientfor the purpose for which it is used.

With the above and other objects in view the invention finally consistsin the novel construction, combination, and arrangement of parts whichwill be hereinafter more fully described and then specifically pointedout in the claims, and, referring to the drawings ac-- companying thisapplication, like numerals of reference designate corresponding partsthroughout the several views, in which Figure 1 isa side elevation of myimproved fuel-burner. Fig. 2 isavertial sectional view of the same. Fig.3 is a transverse sectional View taken on the line a w of Fig. 2. Fig. 4is a fragmentary sectional view taken on the line 1/ y of Fig. 2, andFig. 5 is an enlarged fragmentary sectional View of a portion of theburner.

To put my invention into practice, I construct the burner of a tubularbody 1, preferably formed of one piece of metal by casting. The body 1is provided longitudinally of its length with a central bore 2, servingfunctionally as an air-inlet to my improved fuel-burner. Formed in thebody portion 1 and surrounding the bore 2 is an annular gascompartment3, having an inlet 4:, said inlet being formed by providing the body 1with a boss 5, having a screw -threaded aperture formed therein adaptedto receive a suitable gas-supply pipe. (Not shown.) The body portion 1,diametrically opposite the gas-inlet l, is provided with a boss 6,havingascrewthreaded aperture 7 formed therein, in which ascrew-threaded plug 8 is secured. The aperture 7 is provided, wherebythe interior of the annular gas-compartment can be readily cleansed atany desired time. In forming the body 1 I provide the one end of thebody with an annular beveled edge or face 9, the formation of saidannular beveled edge providing a similar surface upon the interior ofthe annular gas-compartment 3 at one end thereof. The beveled edge orface 9 is provided with a plurality of circumferentially-arrangedopenings 10, the respective rows of openings 11 and 12 being staggeredlyarranged. Each opening formed inthe beveled edge or face 9 is madetangential to, the axes or radii of the central bore 2, as illustratedin Fig. 3 of the drawings. In order that the direction of the openings10 can be readily understood, I have illustrated in Figs. 4 and 5 of thedrawings enlarged detail fragmentary sectional views of the beveled edgeor surface 9. In connection with these figures it will be observed thatthe apertures are drilled upon a plane at right angles to the bevelededge or surface 9 and tangential to the axes or radii of the bore 2. Thebody 1, upon its end corresponding to the beveled edge or face 9, isprovided with a peripheral enlargement 14, having threaded apertures 15formed therein. Attached to the end of the body 1 is a threaded collar16, said collar having a pierced flange 17, through which screw-bolts 18pass and engage in the threaded apertures 15.

The reference-numeral 19 designates a cylindrical body, which servesfunctionally as a mixing chamber, and this body is screwthreaded uponits one end, as indicated at 20, whereby it can be secured in the collar16, adjacent to the beveled edge or face 9 of the body 1.

When gas is admitted to the body 1 through the opening 4, the gas passesaround the annular compartment 3, and when the pressure or intensity ofthe gas is suflicient it is ejected through the openings 10 of thebody 1. The direction at which the openings are drilled causes the gasto be ejected in a spiral form, the gas adhering closely at first to thesides of the body or mixing-chamber 19, then gradually circulatingtoward the center of the mixing-chamber, where it encounters airentering the burner through the bore 2. A draft or suction is created bythe passage of the gas into the mixing-chamber and air is drawn into themixing-chamber rapidly, effecting a perfect mixing and commingling ofthe gas and air prior to its ignition, and consequently increasing theefficiency of the burner.

The particular feature to which I desire to call attention resides inthe simplicity of the burner-body and the peculiar formation of the oneend thereof, which assists materially in the mixing and commingling ofthe fuel and air admitted to the burner.

It is obvious that the fuel-burner is susceptible to various changeswithout departing from the general spirit and scope of the invention.

What I claim, and desireto secure. by Letters Patent, is'

1. A burner of the type described comprising a body having an annulargas-receiving compartment in its walls, with inclined faces at one endof said chamber, and having openings extending through said inclinedfaces and tangential to the axes or radii of the body, the said bodyhaving an annular port leading to the gas-receiving chamber, a collarsecured to one end of the said body, and a mixingtube connected to saidcollar, substantially as described.

2. In a fuel-burner a hollow body having double walls forming a spacebetween them constituting a gas-receiving chamber and an inlet-port tosaid gas receiving chamber, the inner wall of said body being at anobtuse angle at one end, and having openings extending therefromtangential to the axes or radii of the body, acollar bolted onto the endof said body and a mixing-tube securing said collar, substantially asdescribed.

In testimony whereof I afiix my signature in the presence of twowitnesses.
